Titi, you're right on the mark.
I like the last one best, but I'm trying to find my own...
I'll edit my post when I find something. The only thing I have against the last one is that Dark Magic is not undeads; the two forehead horns are cool though and could probably be added to another design. Or, we could just make the skull a human(oid) head.
I found five:

These last two are in for good measure.
I like the staff of the first, the head of the second (but the horns from your last one should be added), and the overall body type of the third image. On the last picture of yours, the shoulders have some kinds of pointy thingies (I don't know what to call it
) and there is a sort of vest in the front. I like the shoulder things and the vest in the front as well. I like how my third image kind of has spines down the back, like a monster, but it doesn't look too foreign as to be inappropriate to Dark Magic. Because you see, this faction is all about humans which have learned a sinister trade: Dark Magic. And if you guys are wondering why I haven't told you yet, it's because I just figured that out.
//Edit: I forgot, but it is also important that the Acolyte not have any obvious weapon on it, because it doesn't actually attack. This is simply because I saw all of the bad things the Magic AI does with the Initiate, so I am trying to make it more like the Worker from Tech, which the AI handles better.
